Taalfwhom'z't may concern: t I i Be it known that I', Jo LY"L,i MoR-Ris,' a

citizen of the United Sta'tes, residing at Grafton, in the county of Allegheny and State of Pennsylvania, have'i'nvented cer-' tain new and useful Improvements in Automatic \Veighing Apparatus; and Ido hereby i declare the following Itobe' a full, clear,

and exact description of the invention,-such as will enable jothei-s skilled in the art to which it appertains to make and use the same, reference being had to'the accompany ing drawings, and to the letters and figures of reference marked thereon, which form a part of this specification. V

This invention relates to new and useful improvements in weighing devices and has particular reference'to such devices especially adapted for weighing dry materials.

The primary object of the invention is the provision of a weighing device of this character which WlllfiUtOHlHtlCtIlly cut off the discharge of material to the scale when a predetermined amount of material has been deposited. I Y

.A further object of the invention is to provide a combined weighing scale and bin, the scale being supported by the bin in such a manner that the platform thereof is directly under the discharge spout of the bin.

My invention is illustrated in the 'accoin panying drawings, in which Figure l is a perspective view of a combined bin and weighing scale.

Fig. 2 is a side elevation.

Fig. 3 is an end elevation.

Reference IIOWbElHg had to the details of the drawings by numeral, 5 indicates a bin having a hopper bottom (5, inclined to an outnected thereto by means of the pivot pin 10,

said pivot pin 10 being disposed at a point to the right of the center of the yoke 9 to permit the-upper ends of the standards 10 to be supported centrally thereof.

Arranged centrally of one end ofthe yoke 9 is a graduated beam 11 having notches 12 provided in the upper edge thereof, to

receive the knif'e'like edge 13 of tlie poise i-le', operating along said be m llto' balancethe material beingweighedm The discharge spe t *7 has a slot l5 "pro vided in one side thereof,'- the' slotial5 "com:

municatingwith guide "15 e and through thisslot and guide operates a slidable cuto'if valve 16, "having an' in tgral' arin"17 .spaced from the bottom of the hopper 6, and

operating through guides 18 depending from the under side thereof. A cam 19 is formed on the 'outeredge of the arm 17 and cooperates with a cam 20 formed on the lower end of the vertically operating rod 21 which operates in guides 21 and. 22, and it will be seen that movement of the rod 21 produces has one of its'ends pivotally connected to I the yoke 9'by' pivot'pin 23, the opposite end being'connected to the rod 21 by means of the pivot pin 24.

The lower ends of the standards 10 sup- 'ort the platform 25 which is held thereon y the brace rods 25' extending angularly therefrom. It might be further stated that a Weight 26 is adjustable along the yoke 9 to balance the weight of the platform 25 for holding the yoke normally evenly ba1- anced. Pins 27 and 28 are positioned on the bin and in spaced relation, the yokeoperating therebetween, and it is obvious that the yoke engages the pins'27 and 28 when the Same is oscillated, thereby restricting the movement of the yoke 9.

The operation of the device is as follows :'-The poise l4 having been placed in its desired position along the beam 11, a bag or other receptacle is positioned on the platform 25 and, when the weight 14 is overalanced by the weight ofthe material on the platform, the rod 23 causes the cams l9 and 20 to cooperate to-move the rod 17,

the discharge spout 7 is cut off. What I claimto be new is 1. In combination with a bin having a discharge opening, a weighing scale including a yoke extending around the bin and pivotally connected thereto, a platform pivotally connected to the yoke, a cutofl valve result that the discharge of material through thereby moving the cutoff valve 16 with the V operating iii the, discharge spout, a horidischarge opening, a Weighing scale includzontally operating rod connectedtoithe cutoff valve, a 'vertically operating rod connected to one end of the bin and having connection with the yoke, and means on one end of each of the rods for cooperating,

whereby movement of one rod will produce.

arelative'mo ement of the other rod.

2. In combination with a bin havlng a Copies of this patent may be obtained for horizontally operating rod having a cam surface-on one end thereof adapted to cooperatewith the cam surface of the first mentioned rod, the opposite end of the horizontallyoperating rod having an integral Valye member operating in the discharge spout'for cutting off the discharge of mate- .rial through the spout, and a welght on the yoke for balancing the platform.

In testimony whereof Ihereunto aflix my 25 signature in the presence of twowitne'sses.
